I am doing business of rental of immovable property on commercial purpose i.e. marriage hall, etc where parties performing their program from inter state or intra state. 

For parties who conducted their business promotional program  (GST Registered Parties) at my premises, I charge IGST as they wanted to take credit at their state, but my CA asked me not to charge IGST  instead charge CGST/SGST.  In this case how can paty take credit? for tax paid for business promotinal purposes??

anybody can answer?  My CA asked me to revise bill from IGST to CGST
